Rest & Recover Collagen

The formula for real recovery.

Rest & Recover is built around four clinically dosed active ingredients, each chosen for a specific role in sleep quality and overnight physical repair. No melatonin. No dependency. No next-day grogginess.

What's in it and why:

  • 300mg GABA — calms neural overactivation and eases the transition into deeper, more restorative sleep stages
  • 250mg magnesium — the bisglycinate form for maximum absorption; replenishes the magnesium depleted by training and supports overnight muscle repair
  • 200mg L-theanine — drives alpha-wave activity in the brain, producing a calm wind-down without sedating you
  • 10g hydrolyzed collagen peptides — grass-fed Argentinian beef, yielding ~3g glycine; the amino acid profile your body uses for tissue repair, delivered during the overnight window when synthesis peaks
  • Informed Sport certified • Made in the USA
Title

Rest & Repair

More than a Sleep Aid

  • Wake up Stronger, Less Sore.

    10g collagen delivers the amino acids your muscles and connective tissue need during the repair window — so training adaptations actually stick.

  • Fall Asleep Naturally.

    Magnesium bisglycinate and L-theanine bring your nervous system down from your day. So you can fall asleep on your schedule.

  • Clear Head. No Hangover.

    Unlike melatonin, nothing in Thirdzy interferes with your hormones or leaves you foggy. Take it every night. No tolerance, no dependency.

What to Expect Over 30 Nights

  • After 1 Night

    You went to bed and actually wound down. The mental noise quieted faster. You woke up feeling like sleep did something — not just passed.

    • Calmer before sleep
    • Deeper sleep
    • Easier to wake up

  • After 7 Nights

    The pattern is forming. You're falling asleep faster, staying asleep longer, and waking up with more in the tank than you're used to.

    • Falling asleep faster
    • Staying asleep through the night
    • Waking up ready

  • After 30 Nights

    This is what consistent recovery sleep feels like. Less soreness. A body that's actually keeping up with the work you're putting in.

    • Stronger training sessions
    • Less soreness and stiffness
    • More energy in training

Ingredients Backed by Science

This is Who Needs Rest & Recover

You train hard but wake up under-recovered

You're putting in the work. Thirdzy makes sure your sleep is putting in the work too: deeper recovery cycles, less soreness, more ready every morning.

You're sore more days than not

That's your body telling you the overnight repair isn't keeping up. Thirdzy delivers the collagen and amino acids your muscles and joints need to rebuild while you sleep.

You can't always get 8 hours

You're not going to fix that. Thirdzy makes the hours you do get more restorative — so a 6-hour night recovers you like an 8-hour one used to.

You sleep but never feel fully rested

Hours in bed isn't the problem. Sleep quality is. Thirdzy supports deeper, more restorative sleep cycles so you actually wake up feeling like you slept.

You're done with melatonin

The grogginess. The dependency. The way it stops working. Thirdzy supports deep sleep without overriding your body's natural sleep signals.

Frequently Asked Questions
View all FAQs

CAN I TAKE IT ALONGSIDE MY OTHER SUPPLEMENTS?

Yes. Rest & Recover is designed to fit into an existing supplement routine. It contains no stimulants, no hormones, and no ingredients that interfere with common training supplements — protein, creatine, pre-workout, or fish oil. The one thing to check: if you're already taking a separate magnesium supplement, you may want to account for the 250mg magnesium bisglycinate in each scoop to avoid exceeding your daily intake. If you're unsure, check with your healthcare provider.

IS IT SAFE TO TAKE EVERY NIGHT LONG-TERM?

Yes — that's how it's designed to be used. None of the four ingredients in Rest & Recover create dependency or tolerance. There's no melatonin to suppress your body's natural production, no sedatives, and no hormones. The collagen, magnesium, GABA, and L-theanine are all naturally occurring compounds your body already uses. Nightly use is not only safe — the effects are cumulative, meaning your sleep quality and recovery continue to improve the longer you use it consistently.

HOW DOES IT COMPARE TO AGZ?

AGZ (popularised by Dr. Andrew Huberman) is built around mental relaxation — magnesium L-threonate, ashwagandha, saffron, and valerian root target cognitive calm and stress reduction. It's a solid formula if your primary goal is unwinding mentally. Rest & Recover shares the L-theanine, but the rest of the formula is built around physical recovery: 10g collagen delivers the amino acids your muscles and joints need to repair overnight, GABA directly quiets neural overactivation from training, and magnesium bisglycinate supports muscle relaxation specifically. AGZ can help you relax. Thirdzy helps you recover while you sleep.
